4 Claims.

This invention relates to a punch. More particularly, it relates to a hand operated punch adapted to punch either shallow or deep notches along the margin of a card or the like.

Record and statistical cards, checks and. other paper records and documents are frequently provided with marginal perforations to enable coding to be notched into their marginal edges. Such cards or sheets are coded for classification by notching the cards marginally to provide an open notch or slot extendin from the edge of the card to one or more of the marginal perforations. A group of cards, checks or the like so coded and classified may be sorted by means of sorting needles or rods, which are extended through the marginal perforations in'a manner which is well known.

Marginally perforated cards, checks and the like such as referred to are usually supplied to the user without notching and are notched by the user according to his particular classification requirements. In small installations it is a common practice to notch such perforated .cards by means of a hand punch. Such punching involves diniculty where two rows of marginal perforations are provided, including an'outer row near an edge of the card and an inner row farther from such edge. It is necessary to punch out certain notches to the outer row of perforations and others to the inner row of perforations.

It is an object of the present invention to provide an improved hand operated punch which can be quickly and accurately manipulated to punch either a shallow punch or a deep punch.

It is a particular object of the present invention to provide a hand operated punch which may be easily and accurately adjusted to punch out shallow notches along the edge of a marginally perforated card, check or the like, to either the outer or inner row of perforations, as desired.

These and other objects of the invention will be apparent from the ensuing description and the appended claims.

One form which the invention may assume is exemplified in the following description and .illus-' trated by way of example in the accompanying drawings, in which:

Fig. 1 is a longitudinal section through the punch.

Fig. 2 is a plan view of thesame.

Fig. 3 is a bottom view of the same.

Fig. 4 is .a transverse section taken along the line 44 of Fig. 1..

Fig. 5 is a fragmentary view of a'marginally perforated card punched to provide a shallow 2 notch and a deep notch by means of the punch of the invention.

Referring to the drawings, there is shown a punch I comprising a main housing 2 having an upper section or chamber 3 and a lower section or chamber 4. A shelf 5 is provided between and extending the length of the upper and lower chambers, and upper and lower assembly members .8 and l are provided, as shown, having terminal flanges B abuttin the ends of the housing. Screws 5! in threaded engagement with the reinforcing members and the shelf are provided to hold these members securely in place. Th assembly members 6 and l are also provided with side flanges 22 and 22a, respectively, and assembly pins l! are provided, as shown, each pin it passing through the side flanges 22 or 22a and the side walls of the housing.

A di plate 169 is attached to the forward end of the assembly members-t and 1', said die plate having a die opening 5:3 shaped to cooperate with the punching member 29.

A punching member .26 is provided, being pivotally supported by a pin 21 secured to and extending between side flanges 22 of the upper assembl'y member 6 and having a forward arm 23 and another arm 24 extending downwardly through an opening 25 formed in the shelf 5 and assembly members ii and l, and also extending rearwardly. An operating handle 26 is provided for actuating the punching member, such handle being secured to the punching member 20 by a pin or screw 2? and being pivotally supported upon the pivot pin 2!. The handle 25 extends through a bottom opening 28 formed in the lower chamber 4. The forward arm 23 of the punch is provided with a head portion 29 including a stepped punching blade 30 having a rearward section 31 for cutting shallow notches and a forward section 32 for cutting deep notches as described hereinafter. ihe head portion 29 is also provided with a hatching gauge 33 at the rear of the rearward section 31 for a purpose described hereinafter.

The handle 25, and with it the punching mem her 255, are normally maintained in the position shown in Fig. 1, that is to say, the are urged in a clockwise direction, by means of a coil spring 3? compressed between a collar 38 on a pin it secured to the handle, and a socket it for-med in the lower assembly member and shelf. An adjus'table stop member 43 is provided for the purpose of forming deep or shallow notches as desired, such member being pivotally supported upon .a pin 44 extending between and through the side walls of the handle. The stop member 43 extends through an opening 45 formed in the handle 26 and it also extends into an opening 35a formed in the shelf and assembly members 5 and 'l. Th stop member E3 is also provided with a trigger it, an upper shoulder ill and a lower shoulder it and it is urged in clockwise direction by means of a coil spring 4;) compressed between a socket 58 formed in the lower arm of the punching member 2:] and a socket 5! formed in the stop member it, so as to cause the lower shoulder 48 to abut against the bottom wall of the handle as shown in Fig. 1.

A chips or cuttings receptacle 52 is also provided at the forward end of the punch, such receptacle having an open top adjacent the die opening 53 to receive the chips or cuttings and having a bottom opening or door 56 and with a slide 55 serving as a closure for the bottom door. A button having a scored surface 5? is provided, being secured to a pin 6%] fastened to and engaging the slide and secured, at its upper end, to a spring iii, the pin being received within a slot $2 formed in the bottom of the receptacle.

In operation, a marginally perforated card, check or the like indicated at 65 is inserted in the punch as shown, so as to abut the notching gauge For accuracy of alignment of the punching head 2% with the perforation which it is desired to notch out to the edge of the card, two markers 86 are provided (see Fig. 2) on either side of the punching head. If it is desired to punch out a shallow notch 6'1 to an outer perforation 68, as shown in Fig. 5, the handle 26 is squeezed inwardly against the coil spring 3! until the upper shoulder ll of the stop member 43 abuts the lower assembly member 'I. The shoulder 41 is so disposed as to abut the assembly member 7, and thus stop further pivotal movement of the punching member Ell, after the rearward section 3! of the punching blade 3d has punched a shallow notch but before the forward section 32 has been brought into contact with the card 65. If, on the other hand, it is desired to punch a deep notch $9 to an inner perforation it, the trigger 46 is squeezed inwardly, thus pivoting the stop member it to cause the upper shoulder 47 to clear the reinforcing member I, and at the same time the handle 2%; is squeezed inwardly to its limit. The punching member 2i] will thus pivot further causing the forward section 32 to make a deep punch. To provide adequate clearance for the handle 26 in making a deep punch, a notch 42 is provided therein, which receives the rear assembly pin 4!.

To disassemble the punch for repairs or the like,

the assembly pins ii are knocked out, the upper and lower chambers 3 and 4 are disengaged from the assembly members, the punching member 20 and handle 25 are removed by knocking out the pivot pin 2 5, etc. The parts are readily re-assembled, as will be apparent.

It will thus be seen that a hand operated punch has been provided which is simple in design, which can be readily disassembled for repairs, if necessary, and which is easy to operate and is effective to punch out deep or shallow notches as desired.

While I have shown the preferred form of my invention, it is to be understood that various changes may be made in its construction by those skilled in the art without departing from the spirit of the invention as defined in the appended claims.

Having thus described my invention, what I claim and desire to obtain by Letters Patent is:
